How to use

Attach the lavalier microphone to clothing near the speaker's mouth, typically on the lapel or collar, ensuring the capsule faces outward and is secured to minimize rubbing. Pair the transmitter to a compatible receiver tuned to the 863.1 MHz frequency and verify clear signal reception before starting. Adjust gain on the receiver or connected mixing device to achieve a clear, distortion-free vocal level, and check monitoring to avoid feedback in live situations.

Usage recommendations

Position the microphone 15–20 cm from the mouth and avoid placing it directly against fabric to reduce handling noise. Perform a soundcheck in the actual environment to identify sources of interference and set receiver gain conservatively to preserve headroom.
